Embodiment
The most basic a kind of embodiment of the present invention, as shown in Figure 1, an end of bearing plate 2 maintains an equal level through positioning shaft 21 and road surface 1; The other end of bearing plate 2 is supported by load-bearing pillar 23 after decline; Remain in the road surface and maintain an equal level, oil hydraulic pump 31 is installed on bearing plate 2 belows, and Returnning spring 22 is installed on the place of bearing plate 2 belows near the load-bearing pillar direction; After vehicle driving is crossed bearing plate 2, bearing plate 2 is raised to certain altitude, present embodiment is 10cm;
Bearing plate 2 moves downward on it the time at automobile running; Piston to oil hydraulic pump 31 does work; Be delivered in first accumulator 33 through one-way valve 32 behind the liquid pressurized in the oil hydraulic pump 31; When the liquid that stores in the accumulator 33 reach set numerical value after, be delivered in the pressurized machine 35 after the supercharging once more to be delivered in second accumulator 37 through one-way valve 34 and store through one-way valve 36;
After the liquid that stores in the accumulator 37 reached and sets numerical value, through the sequence valve 41 and 43 work of adjustable restrictive valve 42 driving liquid engines of adjustable activation pressure, liquid engine 43 generated electricity through speed changer 44 speedup rear driving generators 45;
Liquid after the work is back in the liquid storage tank 3 through filter 46, and filter can add as required and join condenser;
Accumulator 33 all is equipped with relief valve 38 with accumulator 37, when the load overload is that excess liquid is back in the liquid storage tank 3 through relief valve;
Through one-way valve 39, the liquid in the liquid storage tank 3 is inhaled back after oil hydraulic pump 31 work are accomplished, formed a loop.
It more than is a workflow.
Below be the laboratory data of present embodiment:
Select a descending highway section; The weight of vehicle is 1000kg; The length of bearing plate is 4 meters, and (longitudinal separation of normal wheels is 3.6 meters, has also partly that the wheel longitudinal separation of car surpasses 3.6 meters, and it is preferable to be made as 4 meters long or shorter meetings; So just can reach and make a back car can't reach bearing plate, a car on bearing plate crosses; The long meeting of bearing plate lets bearing plate can't rebound reset cause the efficient very low on bearing plate because of the multi-section vehicle goes simultaneously), the height that lifts is 10cm, the piston area of oil hydraulic pump is 0.01m 2, the capacity of accumulator is 12L, and the pressure ratio of pressurized machine is 1: 10, and gearbox is 10 times of speed changes, and engine model is WD145-400, and parameter is 385cc/rev150rpm, requires 60 liters oil, and pressure is 97BAR.
When vehicle driving in bearing plate top owing to be the descending highway section, the length of 4m, the height 10cm of local terminal can not increase automobile fuel consumption, and oil hydraulic pump can promote the oil of 1L and is delivered in the accumulator, according to the formula of gravity accleration:
1000kg x 9.81=9810 newton/0.01m 2=981000PA=9.81bar;
Learn that thus the pressure that bearing plate brought is 9.81bar;
1L9.81BAR liquid through after 1: 10 the pressurized machine supercharging, the pressure of 0.1L liquid is 9.81bar, after 20 bearing plates are crossed in 1 above garage of 1000kg, the liquid of 2L98.1BAR will be arranged in the accumulator;
After having 30 automobiles to cross 20 bearing plates in one minute, accumulator will have the liquid of 60L98.1BAR, and the motor of the liquid driven 385cc/rev150rpm of 60L98.1BAR can produce the merit of 480 Ns of rice in the accumulator;
The merit of 480 Ns of rice can reach 1500rpm after through 10 times of speed changes in theory, can drive generator and carry out work;
The merit of 480 Ns of rice is through having 10~20% loss behind the gearbox in the actual experiment, calculates 480 Ns of rice according to maximum loss 20% and advances loss 20% after 10 times of speed changes:
480 Ns of rice x1500r/9554=7.5KW
7.5KW?x(1-20%)=6KW
That is to say, when having 30 garages to cross 20 bearing plates in one minute time, can produce the energy of 6KW above 1 ton.
Deceleration strip embodiment of the present invention, as shown in Figure 2, the piston 31 of oil hydraulic pump is designed to semicircle shape is raised in 1 top, road surface; Vehicle driving is out-of-date; Piston 31 is depressed, and Returnning spring 22 is positioned at piston 31 belows of oil hydraulic pump, and vehicle driving resets to piston 31 later.
More efficient a kind of embodiment of the present invention, as shown in Figure 3, can bearing plate 2 design lengths are shorter, raising height is lower, present embodiment length 1m, raising height 3cm;
Such design is applicable to the highway section that the road traffic vehicle is busy, because bearing plate 2 length are merely 1m, even can be shorter, vehicle driving be on it the time, and front and back wheels all can be done work to the piston 31 of oil hydraulic pump; Rolling is crossed 22 pairs of bearing plates 2 of bearing plate 2 back Returnning springs and is resetted before the vehicle, and trailing wheel continues to roll bearing plate 2, and the piston 31 of oil hydraulic pump do work once more, and the utilization rate of such design oil hydraulic pump is higher, and is still also stronger to the life requirements of Returnning spring 22.
Above-mentionedly be merely three specific embodiments of the present invention, anyone can draw other various forms of road pressure power generating systems under enlightenment of the present invention.All equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
